TOOL FOR'FINISHING METAL SURFACES OR THE LIKE.

SPECIFICATION forming part of Letters Patent N0. 700,825, dated May 27,1902. Application filed February 18, 1901. Serial No. 47,891. (Nomodel.)

To all whont it may concern: 7

Be it known that I, ISAAC BITTER, Jr. a citizen of the United States,residing at No. 1816 Hamilton street, in the city of Philadelphia,county of Philadelphia, and State of Pennsylvania, haveinvented anew anduseful Tool for Finishing Metal Surfaces or the Like, of which thefollowing is a specification.

My invention relates to improvements in tools for finishing metalsurfaces and the like;

and the objects of myinvention are, first, to

provide two substantially parallel knives for scraping the surface to befinished; second, to support said knives so as to enable them to alwaysadapt themselves to the surface to be finished, and, third, to providemeans of securing said knives so as not to interfere with their action.I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of a tool embodying themain features of my invention, showing the tool attached to aboring-bar.

Fig. 2 is a front elevation of the same. Fig.

erably curved or are shape, and from the exterior face of this plateprojects one or more knives or scraping edges a. One end of this plateis connected, preferably, by a link. a to the bracket d, so -as topermit the tool a to swing eccentrically to the support 0. Where, as inthe instance shown, the support 0 isa boring-bar, the tool a and itsknives a are normally concentric with the periphery of the bar 0, butmay swing toward or away from the periphery of the bar 0 by reason ofthe .fiexible connection or link e between one end of the tool a and thebracket (1. To maintain the tool at in normal concentric relationshipwith the support c, a resilient block b is interposed between the innerface of the tool a and'the periphery of the support a.

r In the modification illustrated in Fig. 3 the bracket g' slidesradially in a slot of the borin g-bar h and may be fixed to the bar itwhen properly adjusted by bolts or other fastening means. The bracket ghas a shoulder 9 concentric With the periphery of the bar h, and betweenthis shoulder g and the back of the tool a, the resilient blockb isinterposed. The tool a is connected to the end of bracket 9 by the samelink connection (5 as hereinbefore used with the bracket d in the formillustrated in Figs. 1 and,2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a tool of the character described, a support, a' curved orarc-shaped tool provided on its outer face with cutting or scrapingedges and normally arranged concentric with the periphery of thesupport, means for flexibly connecting one end of the tool to theperiphery of the support so as to permit the tool to swing eccentricallyto the support and resilient means interposed between the inner face ofthe tool and the support.

2. In a tool of the character described, a scraping-tool comprising acurved plate provided on its outer face with scraping edges, a centralsupport, a resilient means interposed between the plate and the support,and a link for connecting one end of said plate to said support andthereby permitting the plate to swing eccentrically toward or away fromthe periphery of the support.

In testimony whereof I have signed my name to this specification .in thepresence of two subscribing witnesses.
